Abstract
Embodiments of the present invention provide a machine, program product, and computer-implemented method to select a fit-for-purpose tool for reservoir saturation monitoring. A computer stores a plurality of characteristics for a plurality of well-logging tools, including open hole and closed hole resistivity, pulse-neutron spectral carbon-oxygen, and pulse-neutron capture technologies, as well as a predetermined ranking of tools within a technology. The computer obtains user inputs associated with conditions of a candidate well, e.g., a minimum tubing restriction, whether the wellbore is open or cased, and whether the well is a wet producer. Inputs can also include an objective of the reservoir saturation monitoring, such as, evaluating sweep efficiency or identifying remaining pay for sidetrack or perforation. The computer compares the characteristics for the well-logging tools to the user inputs and determines a well-logging tool selection responsive to the comparison to thereby recommend a course of action for the candidate well.
